I have the L2461xwA Lenovo Widescreen Touchscreen display. When I set the resolution to 1680x1050, it is full screen as expected. When I set the resolution to 1920x1080, which is the native resolution, it is NOT full screen. There is about a 1 inch black border on the left and right sides and about a 3/4 inch border on the top and bottom when in 1920x1080 resolution. How do I make it full screen?

(I'm running Windows 7 64-bit and have installed all of the drivers. The touch functionality and camera are working great)
